Adjustable text sizes, and even better, adjustable HUDs in general. Not every game can do this, but how FFXIV does it where you can adjust the size and placement of every piece of the HUD is a dream come true.
It’s gotten better I feel like in the last couple years, but the switch from HD to 4K made all the text so freaking small I couldn’t play anything on the TV in my living room and had to go sit close to a computer monitor instead.
Oh yeah, this 100%!
